What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at how a person's genetic makeup influences their response to oral semaglutide (Rybelsus), a drug used for type 2 diabetes. Researchers will give 125 adults with prediabetes a 14-day course of the drug and measure blood sugar, insulin, and other factors after a standardized breakfast. The goal is to understand why some people respond differently to the medication, which could lead to more personalized treatment for diabetes.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
oral semaglutide (Rybelsus)
What this could lead to
If successful, this could help doctors predict who will benefit most from semaglutide based on their genes, leading to more personalized diabetes prevention.
What could go wrong
This is a small, early-phase study focused on understanding mechanisms, not proving treatment effectiveness. Results may not apply to everyone, and the 14-day treatment period is too short to assess long-term outcomes.
